After saying a lot of words, Jing Hongtu was also a little depressed. He seemed to be aging very quickly, and his energy was not as good as before.

He stacked the books in Xiang Shan's hand one by one, as if he wanted to give him the entire study.

He suddenly sighed: "I seem to have put too much pressure on you. For me, having you take over the position of head of that research department is probably the greatest achievement of my life, and it's no exaggeration to say that it is. As the person who develops the technology, you're doing it even more beautifully than I've ever daydreamed before. You have bridged wars, brought about development, and are on the verge of extinguishing famine. Perhaps poverty will also be a thing of the past...... When the world was at its worst, I never dreamed of such a good thing. ”

"I probably won't be able to accomplish anything more than this in the rest of my life. I really hope you can win, Xiao Xiang. In the constant battle, get the final victory. ”

Xiang Shan felt the weight of the book in his hand. Paper is heavier than bricks and even greater than some stones. Xiang Shan put down the book, bowed his head and said, "Although I haven't taught it officially, I have learned a lot from you. You are my teacher. ”

Jing Hongtu shook his head: "I'm just an external factor. The elements of your awakening to become a self-being were prepared before we went to the Rama project. ”

Xiang Shan smiled: "Don't say anything, it's impossible to make greater achievements...... I see you're still writing? Maybe there are some astonishing academic achievements? ”

"Huh? That one? Science fiction. Jing Hongtu smiled: "After all, I didn't catch this bus." In the past few years, I still want to pick up the dreams of my youth. Want to take a look? ”

Xiang Shan picked up the unfinished manuscript.

Towards the mountain fell into the white paper.

This is my penultimate visit......

Why am I ......? Would like to visit at that time......

The white of the paper turned into another kind of white.

The air was filled with the smell of disinfectant and a faint smell of smoke.

Xiang Shan shuddered.

Late summer 2043. The leaves of the landscape trees outside the window have begun to turn yellow.

Xiang Shan sat on a chair and held an old hand.

It was an old woman. She babbled and said, "Mountain, now you are a big scientist and a big boss." You're busy with you, you don't have to come to see me all the time. ”

"How can that?" Xiang Shan held the woman's hand tightly: "I will be your own mother in my life." ”

His nose was a little sore.

"This kid ......," the mother withdrew her hand and patted him with a smile, "your eldest cousin came to see me two days ago. His son took the college entrance examination this year, and the essay topics were all your speeches at Peking University. ”

Xiang Shan smiled shyly: "That's a trivial ......"

"This is still young, our ancestors have never done such a big thing in their eight lives. The whole family is stained with your light. In the past few days, all distant relatives have come to see me. The mother smiled and said, "Shan, you are a person who does great things, and it is not my turn to worry about this old lady." But Mom, there are still a few things I can't let go. ”

"Mom......" Xiang Shan held his mother's hand again: "Your son has the ability now, he can't do anything." What do you say? ”

"Your grandmother left early, and I don't know if it's this disease. Your aunt also died of this disease. The mother instructed, "You have the ability now, and you have the most professional ...... That's something. Do that screening for the cousins at home. It may be possible to detect and treat it early...... And you too. ”

Xiang Shan bowed his head: "There will never be this disease again." It's true. It doesn't matter if they do. It doesn't matter either. ”

"Yes, yes, know you have what it takes. Boom. The mother smiled: "Don't talk about it." Say something about yours. Xiao Zhu is a good boy...... You two have been together for so many years, why don't you get married? The little girl has never had a name, so she doesn't make people laugh at her. ”

He bowed his head to the mountain. He actually has a lot to say, because he thinks of himself as innovative and progressive. But he didn't say anything.

"When you led the girl home, hey, your father and I don't know how happy we were. He happily drank three glasses of white wine the next day...... Obviously the liver is not good. We both thought you were going to get married soon, and we had grandchildren to hug. But what about you...... Mom didn't mean you. You are all people with great skills, and you are all busy. But no matter how busy people are, they have to have a home, right? It's okay if the child doesn't have time. Lao Xiangjia is not the only one seedling for you, but Xiao Zhu has been with you for so many years, you have to give someone a name, right? ”

"Yes...... "Xiang Shan" lowered his head and threw tears on the ground: "I'll go back...... Organizing...... Wedding ......"

"Oh, don't. Your wedding anniversary will follow my death day, bad luck. Mother's hand covered Xiang Shan's head: "Mom didn't force you...... Don't cry, you kid. I've seen your dad down there, how do you tell him? The son was crying. O mountain...... Mom always hopes that you can live your life happily. ”

Falling forward towards the mountain, the white sheets were shattered by him, and then reassembled into white couplets.

More than 200 years later, in the memory space, the cry of his son was heard.

Zhu Xinyu sat on the opposite side of Xiangshan. This is the edge of the mourning hall. In recent years, the state has advocated frugality and new funeral customs, and the deceased did not like to do a lot of things during his lifetime, so there was no wreath paper money and no complicated ceremonies. The body was surrounded by white chrysanthemums sent by people from all walks of life. Under several large bamboo flower baskets, there are also couplets signed for leaders or embassies.

Zhu Xinyu looked at the recent one "A lifetime with a thick heart, a hundred generations of descendants".

Extremely glorious.

The short ceremony has ended. Only immediate family and a handful of friends remain. It's rare for Xiang Shan to wear formal clothes. He was wearing AR glasses, and his hand was swiping weakly over his forehead, as if he was reading something.

Zhu Xinyu only felt sour and wiped her tears.

It was the autumn of '43.

David and Yagmoth were standing nearby. David is in a black suit with white paper flowers on his chest. Yagmov wears a thick black down jacket. It's still autumn. In terms of the climate of Beiping, Yogmov's outfit is a bit exaggerated.

He said sullenly, "I'm sorry...... Didn't help. ”

David also lowered his head: "I didn't do it, I'm sorry ......"

"A few years ago, when I read a similar industry report, I said that cryonics technology would only take 15 years to be commercialized. Look at it again this year, heh, twenty years. Next time, I'm afraid it won't take twenty-five years. ”

The tone is strange and depressing.

If there is anything that can save the elderly who cannot undergo the genetic modification surgery of the benchmark human, it should be "cryonics".

It's too late for the current technology, but the technology of the future may be possible.

"No way......" David's voice was small.

"I don't blame you." Xiang Shande put it on his forehead, "NASA and CNSA have cut the funding of the Homo sapiens cryonics program and switched to the baseline human cryonics." This technology is for the colonization of outer space. There will be no Homo sapiens astronauts in the future. Baseline man is better suited to conquest of space than Homo sapiens. ”

"The complications of 'species renewal' ...... the medical community are now the focus of the medical community. If there is a breakthrough in this aspect, it will be even more difficult for Homo sapiens to become a benchmark human. As long as you become a benchmark human, 80% of Homo sapiens diseases are not a cause for concern...... Plus prostheticization. We can conquer illness and disability. ”

"However, if we have done such a sci-fi thing as 'changing species', why can't we do 'Homo sapiens cryonics'......"

David was speechless.

The cryonics agency he contacted did not dare to exaggerate the propaganda against the superhuman corporate controllers of this group of monsters. They gave the correct technical information. And according to the judgment of Chen Feng and other experts...... Existing technology does not guarantee that Homo sapiens can be resuscitated after entering cryonics. In addition, even if resuscitation is possible, irreversible brain damage is inevitable.

And, in twenty or thirty years, the research of the medical community will be fully geared towards the benchmark man.

Yogmov kicked the ground with his toes: "If you want to hate, you can hate me." ”

Xiang Shande covered his eyes: "We want to save the world, and seventy percent of the people can enjoy four hundred years of life, get rid of famine, and the merit is immeasurable." I hate you for what you do. ”

"There are significant biological differences between baseline humans and Homo sapiens. The medical technology required by a baseline human is different from that of Homo sapiens. Cryonics protocols for baseline humans cannot be applied to Homo sapiens. ”

The biggest difficulty of cryonics is that when the water in the human body turns into ice crystals, it destroys the body's tissues at the cellular level. There are only two ways to solve this problem. The first is to freeze instantly, so that the water molecules have no time to form ice crystals, and they are fixed in their original positions. The second is to replace the water with a protective solution.

The former is impossible. The level of physics and engineering of human beings has not yet reached the level of instantaneous and uniform freezing of the human body. And Homo sapiens' ability to resist damage is too weak to "take out the brain for quick freezing without injury".

Protective fluid is the more likely path.

However, existing protective fluids are not safe.

The process of replacing the blood with a protective solution has the potential to cause a range of chemical damage.

According to the timetable for the launch of Superhuman Enterprises, within 10 years, the genetic modification of the baseline human will be carried out on everyone. If you're lucky, people born after the nineties can enjoy this treatment.

The cryonics technology of Homo sapiens will take at least more than ten years to produce results, which is a technology that is destined to have a narrow range of applications.

Zhu Xinyu couldn't help but say: "There are so many rich old rich people. Are they willing to ......?"

"Pointless." Xiang Shan exhaled, "Their money is capital. They can't let their capital increase in value, and the capital will be earned by others. They can't draw unlimited funds from the companies under their names, otherwise the laws of the market can sweep them out of the house. They can only invest in the project with the money they can use personally...... How much money can there be? ”

"But what about the state...... If nothing else, so many parliamentarians and electors in the United States have not promised to prepare cryonics technology for the elderly? ”

Yogmov scoffed, "There are a few. But for conservatives, contracting to religious institutions is much cheaper. ”

David shook Xiang Shan's hand: "Mountain...... As long as you want...... At your command, we can set up a project. ”

"There are only so many resources." Xiang Shan put down his hand to cover his eyes and stared at David that Zhu Xinyu had never seen before. He asked rhetorically: "If the technology is more than one day late, about 300,000 people will be disqualified from surgery." A breakthrough of one day early is the well-being of 300,000 people...... What should I do? ”

Zhu Xinyu walked to Xiang Shan's side and hugged his head: "Manpower is sometimes exhausted...... Resources are poor. It's not your fault. ”

Xiang Shan leaned on Zhu Xinyu's chest: "Xinyu ......"

"Huh?"

"I know you don't like your dad...... But he's also an old man. I have time to see him. Xiang Shan looked around: "Let's go and see the old man more when you have time." ”
